Turkish Journal of Botany

We tested the phylogenetic utility of three chloroplast DNA loci, i.e. the trnL(UAA) intron, trnL(UAA)-F(GAA) intergenic spacer (IGS), and trnV(UAC) intron, across thirteen native Oxytropis species. Our objective was to determine whether any of these chloroplast DNA markers could be beneficial to figure out phylogenetic relationships among Oxytropis species. To increase the interspecific sampling, nine sequences of the trnL intron and trnL-F regions were retrieved from GenBank and included in the analyses. No sequence of the trnV intron region was available in the database and so only sequences of the native species were used for the analyses. Phylogenies derived from …
